guards are firmly in place and in good condition.
Immediately replace any worn or damaged guard.

Precautions when driving
Precision steering, tractor adherence, road holding and
efficient braking are influenced by the type of implement,
weight, ballast of front axle, ground or road conditions. It
is therefore of the utmost importance to be cautious in
every given situation.
Groundspeed must be adapted to ground conditions as
well as to roads and paths. Always avoid abrupt changes
of direction.
Be particularly cautious when turning corners, paying
attention to machine overhang, length, height and
weight.
Never use a narrow track tractor on very uneven or
steeply sloping ground.
Never leave the tractor seat while the machine is
operating.
Carrying people or animals on the machine when
working or in transport is strictly forbidden.

Precautions when driving on public roads
Dimensions
Depending on the dimensions of the machine, contact
the relevant authorities to ensure that it can be legally
transported on public roads.
If the machine is over the maximum legal size, follow the
local regulations for special transports of oversize
equipment.
Gross weight and weight per axle
Check that the tractor's authorized gross weight as well
as its lift capacity and maximum weight per axle are not
surpassed.
If necessary, add ballast weights to the front or to the
rear to preserve the steering and braking efficiency.
Always make sure that following ratio is fulfilled:
M x (S1 + S2) < 0.2 x T x i + Z x (d + i)
- i = Tractor wheel wheelbase.
- d = Distance of the front axle from ballast.
- S1 = Distance of the ball joints of lift lower links from
tractor rear axle.
- S2 = Distance of the lower couplings from machine
barycentre (see technical specifications).
- T = Tractor weight + operator (75 Kg).
- Z = Ballast weight.
- M = Operating machine weight.
Transport position
Before transporting the machine on public roads, place
the machine into its transport position, according to the
instructions in this manual.
Lightings and signallings
Before transporting the machine on public roads, ensure
that all legally required lightings and signallings are in
place.
Ensure that lightings and signallings are clean and in
good working order. Replace any missing or broken
equipment.

Maximum speed
Always keep to the legal speed limit for driving a tractor-
machine assembly on public roads.

Precautions when coupling
Before attaching the machine, make sure that it cannot
accidentally start moving (chock the wheels) and that the
parking stand is in the right position.
The machine must only be attached to the hitch points
provided for this purpose.
Never stand between the tractor and the machine when
operating the rear remote control lever of the three point
linkage.
Do not stand between the tractor and the machine
without ensuring that the parking brake is applied.

Hydraulic circuit
Beware! The hydraulic circuit is under pressure.
Maximum pressure at work: 200 bar.
Before connecting hoses to the tractor hydraulics,
ensure that tractor and machine circuits are not under
pressure. Before disconnecting a hose, depressurize the
hydraulic circuit.
To avoid making wrong connections, mark hydraulic
couplers and corresponding hoses with colours.
WARNING! Functions could be reversed (for example:
lift/lower) and cause accidents.
Regularly check the hydraulic hoses. In case of normal
wear, replace the hydraulic hoses every 5 years.
Damaged or worn hoses must immediately be replaced.
When replacing the hydraulic hoses, make sure to use
hoses with the specifications and quality recommended
by the manufacturer of the machine.
To locate a leak, use appropriate means. Protect body
and hands from liquid under pressure.
Any liquid under pressure (particularly oil from
hydraulics) can penetrate the skin and cause severe
injury. If injured, see a doctor immediately, there could
be danger of infection.
Before any adjustments, maintenance or repairs are
carried out, lower the machine on the ground,
depressurize the hydraulics, turn off the engine, remove
ignition key and wait until all moving parts have come to
a complete stop.
Before connecting the PTO shaft, ensure that the PTO
